This microscope is a type that connects directly to a TV monitor via a video cable.

 

Video cable

If your TV uses a BNC terminal, we provide you with the appropriate conversion adapter.

The advantages of this microscope include smoother movement and delay-free display compared to those with a USB connection, which improves visual comfort and is suitable for inspections, etc.

In addition, it is ideal if you want to record videos for a long time, and if you use an HDD recorder, you can record for 24 hours.

On the other hand, the disadvantage is that the resolution is relatively low, but a high-resolution full high-definition microscope is also available. Additional hardware is required to store images, such as a video recorder that supports USB sticks. However, it also has the advantage of being able to use a lot of external equipment, since the video signal is common. It is also possible to transfer images to a PC using USB Video Capture, but the image quality may be reduced.

This article discusses errors that occur when a PC fails to recognize a camera.

 

 

If this errors appear when the PC is unable to detect a camera, primarily due to three reasons:

1. The camera is not connected to the PC or is not directly connected.
2. The camera’s driver software is not installed.
3. Another camera’s driver, such as one for a built-in PC camera, is being used.

 

<Solutions>

 

Please choose Option → Select Device.

 

The Select Device screen will open.

Please select the camera you are using.

 

(If the camera in use does not appear in the window)

There’s a possibility that the driver is not installed, so please proceed with the installation of the driver software.

Some USB cameras themselves have an edge enhancement function, but this time I will introduce an image processing method.

 

There is a technique called Unsharp Mask (USM).
PhotoShop and others also have this function, but there are other software that also has this function.
USM is a type of filter that emphasizes the difference in color between the pixels that make up an image。

 

Before applying Unsharp Mask

 

After applying Unsharp Mask

 

Sharpen images that look blurry throughout.
It is a filter that has the function of highlighting the contours of the image.

 

In addition, our real-time image processing software REAL Effect allows you to view the image in real time and apply contour enhancement to the required level.

 

 

We would like to introduce the height measurement (Z-axis measurement) system. 1. System configuration Install the Z-axis stage and motor controller on the microscope. (Microscope (manufactured by our company) and Z-axis stage (Chuo Seiki) are both general-purpose products.) ）
We use this system, Mitani Shoji’s focus synthesis software, and 3D creation software.
2. How to operate
(1) Focal stacking
(2) Create a 3D image
(2) Create a 3D image: Combine the photo synthesized with a microscope with the position information of the motor to create a 3D image.
From the microscope, you can’t see a vertical or near-vertical surface, so the wall surface is a little more stable, but height measurement can be done without any problems. If there is a slope on the wall, a relatively clean 3D image can be created. As an example, make a 3D image of a dent in a cardboard box.
From here, arbitrary dimensions and cross-sectional shapes can be determined. The yellow line below is an arbitrary line.
Since it is not a measuring machine, there is no accuracy. The smallest step in the Z-axis table (0.5 μ in this case) is the resolution. Depending on how you use it, you can achieve a certain degree of accuracy.

There are various free and paid options available for interval shooting.

 

Our Viewer software, “Measure,” also offers this functionality, but it has limitations with a maximum interval time of 100 seconds and a cap of 999 shots.

 

 

Additionally, we provide extra software that allows for unlimited shots and extended interval shooting durations.

Welding is used in the metal joining process, and the welded area is crucial for product safety. Therefore, inspections such as measuring fusion volume are conducted. The dimensions of fusion are measured on cross-sections to inspect for insufficient fusion, welding defects, clearances, excess fusion, and more.

 

 

＜Preparation＞

Inspection of fusion in the welded area requires the following preparation:

 

①Cutting the test part.

②Polishing the cross-section.

③Etching treatment using chemicals or electrolysis, depending on the material.

 

These preparations are done to facilitate observation and dimension measurement. Leave these pre-treatments to the experts, and we will introduce the perfect product for measuring weld fusion volume.

 

 

＜Capture and Dimension Measurement＞

We promptly captured and measured with our microscope.

 

 

 

 

This involves:

　・Generating reference lines
　・Measuring distances from the intersection of reference lines
　・Creating parallel lines
　・Measuring perpendicular distances from reference lines

 

Repeating these steps can be time-consuming, especially with a large number of samples.

With our measurement software, we offer features that assist in such measurements, reducing inspection time and streamlining the process of measuring weld fusion volume.

 

 

＜Features of the Measurement Software Used＞

 

　①Crossline Generation

By clicking anywhere on the screen with the mouse, you can generate crosslines. If there is any misalignment, you can easily adjust the line position by clicking again.

 

You can also change the color and line width.

 

　② Abundant Measurement Items

There are various measurement items available, which can be used for actual measurements as well as reference lines. When used as reference lines, you can turn off the measurement value display. In particular, ‘Vertical Distance’ was quite useful in this case. Additionally, you can change the display color for each measurement line and value individually.

 

●Two-Point Distance ●Distance Between Parallel Lines ●Horizontal Distance Between Parallel Lines ●Vertical Distance Between ●Parallel Lines ●Vertical Distance ●Distance Between Circle Centers ●Point Coordinates ●Angle Defined by Three Points ●Angle Defined by Four Points ●Circle Defined by Three Points ●Approximate Circle Rectangle ●Ellipse ●Approximate Line ●Arc Defined by Three Points And more

 

　③Automatic Edge Fit Function

 

When you move the mouse cursor close to the line you want to measure, it automatically fits to the edge. This reduces human errors by the operator and allows for accurate measurements.

 

 

 

　④Pinpoint Digital Zoom Function

By scrolling the mouse wheel, you can zoom in or out digitally with the cursor point as the center. This further reduces human errors by the operator. It’s an intuitive feature that allows easy zooming and is very convenient.

 

 

 

　⑤Scale Display

You can display the scale at any desired location with the size you want.

 

 

　⑥One-Click Report Function

　With a single click on the Excel output button, measurement data is transferred to Excel. This allows easy data processing and graph display in Excel. Raw images, images with measurements and lines, and measurement values are all exported to Excel in one click, saving time in report creation. It’s a highly convenient feature.

I want to display crosslines with a high-definition microscope!

 

When it comes to creating lines within images for alignment or using them as reference lines, many of you may be aware that it can be done with a line generator. However, in the end, preparing a separate line generator in addition to the camera and lens can unexpectedly increase the cost.

 

The camera we use in our high-definition microscope already has this line generation feature as a standard. Therefore, you can easily and affordably generate lines without any additional expenses.

 

 

 

What is a High-Definition Camera Capable of Cross Display?

 

Each camera in the High-Definition Microscope comes standard with a crossline display function. In this case, a separate line generator is not needed, and crosslines or crosslines at any desired position can be generated using only the functions of each camera.

 

We will introduce each camera individually.

 

① HIGH-PERFORMANCE FULL HD (HIGH-DEFINITION) CAMERA XM200HD

 

 

 

For the XM200HD, it generates a center crossline in the middle of the screen. The line color is red, and you can’t change the color of it. You can toggle the line display on and off.

Microscopes using the XM200HD include:

　・High-Function High-Definition Microscope TG200XM

　・High-Function High-Magnification High-Definition Microscope FZ200XM

　・High-Function Low-Magnification High-Definition Microscope LRS200XM-MC1

　・High-Function Long-Distance High-Definition Microscope (Stand Type) LRA200XM-S

　・High-Function Long-Distance High-Definition Microscope (Edge-Fixed Type) LRA200XM-E

　・High-Function Coaxial Illumination High-Definition Microscope Z200XM

 

 

② Hybrid High-Definition Camera (with measurement and drawing functions) GR200HD2-MePRO

 

For the GR200HD2-MePRO, it’s a high-definition camera with line generation capabilities (custom crosslines, concentric circles, angle lines) and measurement functions. Line generation is possible at any position, including concentric circles and angle lines. You can choose from 5 different line colors. This model also comes with measurement capabilities.

Microscopes using the GR200HD2-MePRO include:

　・Multi-Function Hybrid Microscope TG200HD2-MePRO

　・High-Magnification Multi-Function Hybrid Microscope FZ200HD3-MePRO

 

 

③ LOW-PRICED FULL HD (HIGH-DEFINITION) CAMERA BA200HD

 

For the BA200HD, it’s a high-definition camera with both custom line generation and crossline generation capabilities. Line generation is possible at any position, and you can also generate a center crossline in the middle of the screen. You have the option to choose from 5 different line colors. It can generate up to 4 vertical and 4 horizontal lines.

Microscopes using the BA200HD include:

　・Low-Cost High-Definition Microscope TG200BA

　・High-Magnification Low-Cost High-Definition Microscope FZ200BA

 

 

In the case of a USB microscope camera

 

In the case of a USB microscope camera, you can use the optional viewer software (MF Ship) to display multiple crosslines.

 

 

 

In the case of a video microscopes

 

As for video microscopes, a line generator is required.

In our company, we also sell a line generator (USB memory-compatible video recorder with split function) GRAV-1.

 

 

 

Optional line generation capabilities, dual-screen display (left/right or top/bottom), still image and video capture, and external trigger-compatible line generators are also available.

With this setup, positioning and alignment with two cameras becomes effortless.

 

Summary

In summary, there are numerous high-definition cameras (microscopes) available that integrate a camera with a line generator for tasks like alignment. You can choose the one that best suits your needs.

As an extra, there are methods involving USB cameras and software, as well as methods using video cameras and line generators.

One cause may be insufficient current supply from the PC.

(This is not noise, etc., and cannot be handled by repeater cables, etc.)

Notebook PCs in particular may have a low total power supply or be in power-saving mode by default.

In this case, a simple solution is to use a self-powered HUB (HUB with AC adapter).

This will ensure that the power supplied to the camera and active cables comes from the HUB and not from the PC.

Self-powered HUBs with ammeter are also available as shown below.

 

A video in which still images taken at intervals are stitched together in succession is called time-lapse, and is also described as time-lapse shooting.

 

It is the exact opposite of a video shot with a high-speed camera (slow-motion video), and is a long shot video played back in a short time.

Therefore, unlike long-term video shooting, it is possible to shoot for a long time with a small capacity.

In addition, since each image is a still image, it is possible to shoot with high resolution.

 

Shooting a time-lapse video is easy without any specialized equipment.

 

How to shoot a time-lapse video

 

(1) Many cameras have a time-lapse shooting function, which makes it easy to shoot.

(2) You can also drop the time-lapse compatible app and shoot with your smartphone.

(3) Take interval shots and save still images. Use editing software to make a time-lapse video.

 

 

How to create a time-lapse video using our products

 

When using our products, the method (3) above is used.

 

In order to take interval shots with our USB camera, we use our dedicated software Hi TriggerQ to take a picture of the object and save a large number of still images.

 

<Introducing Hi TriggerQ> ■ Interval shooting is possible You can set any time for interval shooting. (1 sec ~ 99999 sec) You can also take still images, which is convenient for creating time-lapse videos.   Hi TriggerQ Macro photography using a microscope, line monitoring using a normal fixed-focus lens, etc. If you use our USB camera for any application, you can take time-lapse shooting.

 

First, I tried taking interval shots of the company with the above software.

 

 

 

This is concatenated using editing software to make a video.

There are editing software such as Windows Live MoveMaker, but this time I tried using the free software “Panolapse”.

 

The free version has a limited resolution, so I dropped the resolution of still images.

(The restriction will be lifted when you purchase a license.) 

 

It will be downloaded in the following format.

 

 

When you launch Panolapse .exe, the following screen will start.

 

 

 

Click “Import to Panolapse” to import all the still images taken at intervals earlier.

 

 

That’s all you need to do to get a time-lapse video when you click on the preview button.

 

※Note※

Time-lapse editing software is not our product.

This is an example of this.

 

 

 

For more information on the “Camera USB ” and “Hi TriggerQ” introduced this time, please see the following product page.

Four-screen display shooting software Hi TriggerQ

When employing high-magnification instruments such as microscopes to project images, areas of focus and defocus can occur if the subject is not perfectly flat. This phenomenon can be mitigated by employing focus stacking, which enables the creation of an image with uniform focus.

 

Focus stacking is a technique that combines multiple images, each with different focal points, to produce a single image where everything is in focus.

 

This process can be efficiently executed using our measurement software, MFShip.

 

High-Performance Image Processing Measurement Software MFShip

 

MFShip is a sophisticated image processing and measurement software that offers two methods of focus stacking.

The first method involves selecting and combining already captured images, while the second method, a recommended feature of the software, is known as “rotational synthesis.”

Rotational synthesis is a feature that allows for the instantaneous creation of composite images from real-time video.

 

 

As illustrated in the provided photograph, composite images can be created instantaneously. If you are experiencing difficulties with adjusting focus on your subject, we highly recommend giving this method a try.

There are two ways to display 2 images or 4 screens (or more multiple screens) with a USB camera.

 

(1) Simply use multiple launches of Viewer software that can be started at the same time.
(2) Use software dedicated to multi-screen display.

 

1. Launch the Viewer software at the same time.

It may also be possible with free software.
However, it may not be possible to do it with the same camera, and stability is lacking.
We recommend that you always try it before using it.
(Depending on the software, multiple activation itself may be prohibited.) 

 

The following is a simple trial at our company. (Operation is not guaranteed.) 

I connected two of our cameras and started multiple free software called Amcap to display two screens.

 

In the case of a two-screen display, you can only operate the active screen (left screen above), so if you want to operate the menu, you need to switch screens.

 

2. Use dedicated multi-screen display software.

Since it is software for the purpose of displaying multiple screens, it is stable.
In addition, since there is only one menu, operations such as saving are easy.

The following is a multi-screen display software produced by our company.

 

With a 3 million pixel color camera Example of simultaneous use of a 1.3 million pixel monochrome camera

Multi-screen display Trigger storage software Hi TriggerQ

Features of Hi TriggerQ

You can control multiple cameras, observe both screens, and save images.
In addition to cameras with the same model number, different resolutions and combinations of color and monochrome cameras are also possible.
Of course, you can also use it with one camera!
● Save still images (uncompressed bitmap format / JPEG compressed format) of up to 4 cameras with a trigger signal while live monitoring the video. (Please contact us if you would like more than 5 units.) ）
● The image of the camera is always displayed live. You can shoot while monitoring the video.
● Snapshot function that allows you to take still images at any time
Regardless of the trigger signal, it can also be left in a still image with a mouse click.
You can save a still image on the spot at any time, such as a reference image or a scene of interest.
● Interval shooting is possible.

 

 

High-performance trigger shooting software (Multi-unit version) Hi TriggerF PRO4 / PRO8

Features of Hi TriggerF PRO4 / PRO8 

●  Save/pause still images (JPEG/BMP) with a trigger signal as if releasing the shutter of the camera.

●  Alignment and focusing can be done during live display.

●  4 cameras / 8 cameras (Please contact us if you have more!)

「Even if the camera does not have an external trigger terminal, we sometimes receive requests from customers who want to save images using an external trigger.
In such a case, why not use a ready-made input box?

 

Shodensha’s Viewer software Measure has several shortcut keys.
For example, “Save” is set to “Ctrl+S”.

 

 

Using the ready-made input Box, you can convert the signal from the external switch (external trigger) into a key signal such as “Ctrl+S”. In other words, instead of pressing “Ctrl+S” on the keyboard, you can save the image being displayed in the Viewer software Measure by turning on the external switch.

This time, I tried using “Anything Switch USB” (made by Techno Tool Co., Ltd.) as a ready-made input box.

 

 

The setting method is as follows.
1. Connect an external switch to the terminal of the input box.
2. Connect this input box to a computer via USB.
3. Install the software that came with the input box on your computer.

 

 

4. With the included software, give meaning to the external switch connected to the 1~5 terminals.

 

For example, if you set “Ctrl+S” above as the output when the switch is on, you can save the image at any time using an external trigger.
This completes the configuration.

 

After that, if you turn on the external switch at any time while displaying the image with the Viewer software Measure, you can easily import the image even if the camera does not have an external trigger terminal.
It’s easy to set up, so it’s worth a try.

1. What is grain size?

Depending on the metal material, its mechanical properties (resistance to external forces such as tensile and compressive shear)
The properties of the material are different, and it is necessary to use the metal material according to the application.
In addition, heat treatment changes the metallographic structure and its mechanical properties.
Therefore, this grain size analysis is an important test for product quality assurance.

 

2. How to measure grain size

(1) Visual comparison between standard drawings and metallurgical microscopes (comparative method)
(2) Simultaneous observation and comparison of eyepiece micrometers incorporated into a metallurgical microscope (comparative method)
(3) Incorporate an eyepiece micrometer into a metallurgical microscope and calculate it by simultaneous observation and comparison (cutting method)
(4) Using a camera, there are generally four patterns of soft particle size measurement (counting/quadrature method, cutting method).

 

3. Automatic measurement of metal grain size using software

Although it is the method (4) above, crystal grain size measurement can be performed automatically with software, and efficiency can be improved.

4. More useful functions of grain size software

(1) Comparative method

This is a measurement method by visual inspection. Place a sample of metallographic structure under a microscope,
“Microscopic observation” and “Standard drawing of grain size (×100) JIS G 0551” and “Printed standard drawing”
Compare with an eyepiece micrometer (reticle).
This is the method of obtaining the grain size from the nearest standard diagram.

With this software, you can simply select a standard diagram while observing the microscope camera image in real time.
Calculate the grain size. Microscope camera images are superimposed on standard drawings in real time.
It is a useful feature.

 

(2) Counting/quadrature method, cutting method

The cutting method is to write a pattern (test line) on the captured microscope image, and then
The average line segment length per grain when the pattern crosses the grain is determined, and the grain size is
This is how it is calculated.

< Measurement display example>ASTM (intersection cutting method, section length comparison method)
After measurement, the display shows in blue where the grain boundary rests on the cutting pattern.
* The image example measures a microscope magnification of 100x and a range of 1000 x 1000 dots.

 

5. Conclusion

If you have a lot of grain size measurement, this grain size measurement software has a convenient function
The trick to saving labor is to use it and measure automatically.

1. Observation by the sump method using transmitted illumination with a microscope

In the case of hair, when observed with a microscope, it looks like a black bar even if the magnification is increased.

 

Ultra-High Magnification USB Microscope SH350PC-2R Observed at 600x

 

Therefore, we will introduce the sump method.

What is the < Sump Method? >
There is a method called the “sump method” (*1), in which the structure of the surface of the object to be observed is copied to a very detailed part as if it were a mold, and the copied object is observed. It is ideal for observing objects that do not allow light to pass through, such as the stomata of plant leaves and the cuticles of hair.
*1 A set of sump liquid, sump board, and sump mount can be purchased at RIKEN Trading Company.

It is possible to see the cuticle of the hair even with a metallurgical microscope.
However, metallurgical microscopes are large with a body size of 203 x 255 x 421 (H) mm.

The appearance differs depending on the model and method, so please contact technical support for details.

When looking at metal surfaces with a microscope, it is common to observe with a set of ultra-high magnification microscopes and coaxial illumination.

 

However, when it comes to observing metals, there is a microscope called a metallurgical microscope that specializes in this field, and there is also a method of observing by attaching a camera to it.
(The main body size of the metallurgical microscope is as large as 203 x 255 x 421 (H) mm.)

According to the USB 2.0 standard, it is limited to 5 m.
In fact, cables that exceed this are sold by major manufacturers.
(It is said that up to about 10 m, it does not affect the communication speed much.) 

Not only extension cables, but also the following are also sold.
It is a “USB cable with repeater function”. (It is also called an active cable.) 

 

It is sold by multiple companies, but the product in the photo is

According to the USB cable standard, the maximum length of the cable is 5 m between devices.
However, by using this “USB cable with repeater function”, you can connect devices with a cable of 5 m or more.
For the product in the picture, this cable alone can be extended by 12m.

 

This cable has a built-in signal amplification correction circuit. By restoring the attenuated signal in this circuit, it is possible to extend the cable.
The cable can also be extended to more than 12 meters. In that case, wire as follows.

 

 

I connected a 12m USB cable with repeater function (product in the photo) and the cable included with the camera (1 .8m) to our USB camera, and it worked without problems. However, in the instruction manual of the USB cable with repeater function (product in the photo), there was a sentence that said, “In order to ensure stable operation and recognition, it is recommended that the USB device to be connected is a device that operates on its own power.”
Of course, there are also active cables that use USB power (bus-powered).
It is easy to use without the need for a power supply. However, if your PC’s power supply is vulnerable, it can become unstable.

 

If the USB cable is extended, a voltage drop will occur, so it is recommended that devices (including our USB cameras) that operate by power supply from a PC be sure to check the operation before using it.

Differences between USB 3.0 and USB 2.0

Regular USB3.0 is different from USB 2.0
・Transfer speed：500MB/s
・Compatible or higher with USB2.0
・Maximum cable length 3ｍ
Only the basic parts are shown.

 

Of these, USB3 Vision was created as a “camera interface standard using USB3.0” that can be reliably used for commercial, industrial, and machine vision applications.

Computer Vision

　Stability
　　・High-speed data transmission
　　・Transmit data accurately
　　・Stable recovery from error transmission state
Reliability (compared to connector)
　　・Check and verify accuracy
　　・Fix firmly to the outside part
Was created with a purpose

 

Has the function of resending packets when a transmission error (packet drop) occurs.

→This will virtually eliminate screen freezes that occur with USB2.0.).

 

If the image is saved “from camera → via CPU → memory”, it is called “camera → memory”.

→ Can reduce CPU load.
(Depending on the manufacturer, it is expressed differently, such as “direct memory access,” “no-copy mechanism,” or “DMA.”)

Furthermore, the connector is also used with a screw locking function

Compared to GigE cameras, stability and speed are quite similar.

 

It has the disadvantage of a maximum cable length of 3m, but recently machine vision cables using fiber optic cables have been introduced and they can be used in lengths of 10m or more.

 

Cameras that comply with this standard are marked with the USB3 Vision logo.

Our USB camera CS series and GigE EG camera series are equipped with external signal input so that images can be saved from external signals.
（Optional trigger cable is required for signal input.）

 

However, the standard software does not have the function to save from an external signal, so you will need to use optional software or create a program using the included SDK.

 

There are two main types of optional software that save still images by inputting an external signal.

The main difference is between types that always display a live image while waiting for an external signal and types that do not display a live image while waiting for an external signal but instead display a stored static image with the most recent signal.

 

The advantage of continuous live display is that images can be viewed at all times. On the contrary, saved images cannot be checked unless you access the save folder.

 

HiTriggerQ continuous live display type

 

The advantage of displaying a still image saved using the most recent signal is that you can always check whether the image has been saved correctly.

On the contrary, if you want to watch live video, you need to cancel the state of waiting for external signals.

Still image storage type is saved with the most recent signal HiTriggerF Pro

If you want to program it, please use the SDK located in the camera’s driver installation folder.

 

 

If you want to save images using an external trigger on a camera without an external signal input, you can also use a ready-made input box, etc. to call up an external software shortcut and save the image image.

1. Crystal granularity is

 

There are many types of metals and it is necessary to choose the right metal material according to its use and purpose.
For example, automobile engine parts and general metal parts use different metal materials.
This is because mechanical properties (such as strength against external forces such as tension and shear) vary greatly depending on the metal material.
To evaluate this metal property, it is necessary to observe the crystal structure of the metal structure.

 

The metallic structure is a polycrystalline structure with a crystalline structure consisting of crystalline grains.

In the space between crystal grain and crystal grain there are disordered patches and the boundaries of those patches are grain boundaries.
The granularity of this crystal grain (crystal grain degree) is an important factor that determines the mechanical properties of that metal material.

 

In general, crystallinity refers to the “magnitude of crystal grains” in materials such as metals.

Furthermore, metal structure changes not only by the type of metal material such as aluminum, iron and alloys but also by heat treatment.
Even when the metal or alloy is of the same type, heat treatment will cause the crystalline grains to align in a specific pattern, forming grain boundaries that are different from those before heat treatment.
Therefore, heat treatment changes the grain size and changes the mechanical properties and properties of the metal.
Therefore, grain size analysis is an important test to ensure metal product quality.

 

・Austenitic granules
Consists of twin crystals annealed in the crystal grains of the central face of the cube

 

・Ferrite beads
Does not include twin crystals annealing in the rim line of the centrosomal face

２．Particle size analysis method

①Visual comparison between standard diagram and metallurgical microscope (comparison method)

 

We perform pretreatment such as polishing the metal surface and observe it with a metallurgical microscope.
Grain size was estimated by visually comparing the metal structure magnified by a metallurgical microscope with the “Austenite Grain Size Standard Diagram for Steel (x100) JIS G 0551”.

 

 

 

Metallurgical microscope

 

However, you have to take your eyes off the metallurgical microscope for a while, which is troublesome.

②Comparison of simultaneous observation by incorporating an eyepiece micrometer into a metallurgical microscope (comparison method)

Insert an eyepiece micrometer (reticle) with printed grain size sample into the eyepiece of the metallurgical microscope, and visually observe and compare the enlarged sample and the grain size standard sample to determine the grain size .

This is easy because you can simultaneously observe and compare without taking your eyes off the metallurgical microscope.

 

Particle size scale R1901 manufactured by Shibuya Optical Co., Ltd.

③Calculation by incorporating an eyepiece micrometer into a metallurgical microscope and comparing simultaneous observations (counting/quadrature method, cutting method)

An eyepiece micrometer (reticle) with the pattern printed below is inserted into the eyepiece of a metallurgical microscope, the magnified sample and its pattern pass inside the crystal grain, creating an average line per crystal grain. The method complies with JIS G0551/ASTM E112 standard for length determination and particle size calculation.

④Measuring particle size with software using camera (compatible with comparison method, counting/quadrature method and cutting method)

Additionally, a microscope camera is attached to the metallurgical microscope and automated measurements are performed using the following measurement software.

This method allows automatic and very effective measurements.

G-S Measure particle analysis software (produced by Nippon Steel Technology Co., Ltd.)

◆G-S PARTICLE ANALYSIS SOFTWARE FOR Particle SIZE MEASUREMENT 【Comply with JIS and ASTM standards!】 This is a particle size assessment tool that complies with the following standards. ・JIS Standard (JIS G 0551:2005) ・ASTM standards (ASTM E 112-96, ASTM E 1382-97)   【Can measure up to 12 types of particle sizes!】 ・The evaluation method is to perform up to 12 measurements at the same time by combining the cut samples and calculating the number of grain sizes. 【Cutting pattern can be selected from 5 types!】 ・For cutting method, you can choose from 5 cutting patterns and set spacing and line length.   【Useful for making reports! Excel Output】 ・Particle size measurement results can be exported to Excel (CSV format).     ASTM (intersection cutting method, intersection length comparison method) In the display after measurement, areas with grain boundaries overlapping the cut sample are displayed in blue. *Image example is a 1000×1000 point scope measurement with 100x microscope magnification.

 

3．Conclusion

If particle size analysis is not routine, using an eyepiece micrometer is a cost-effective method.

If you do this regularly, there will be initial costs, but we recommend using a microscope camera to automate measurements with software, as it automates and saves labor.

The software also has other useful functions.

 

The actual field of view of the autofocus digital magnifier is almost the same as the NSZ405 stereo microscope with a 0.5x auxiliary lens attached. (In terms of total magnification of a stereo microscope, it is 3.5 to 15 times.)

Shortening the white wire and the guard wire will activate save mode.

The red line is “unused”.

 

Wireless HDMI transceivers are being sold on the market at relatively low prices.

 

 

This time, after purchasing the above mentioned device, connect it to our HDMI camera to check its operation.
The transceiver is about the size of a cigarette box.

 

		Since the transmitter and receiver each require power, we don’t think there will be much change in terms of wire savings.
		Images can be displayed without lag or color loss.
		There were no problems with displaying categories and adjusting the camera.

 

Please note that this is an introduction only and does not guarantee the operation of all HDMI wireless transceivers.

Our high-resolution cameras’ AC adapter and HDMI cables come straight from the back of the camera.

 

When installing, you may want to shorten the space for this wiring section.
In that case, wiring space can be easily saved by using horizontal connectors.

 

 

Horizontal connector – for HDMI cable (left) – for AC adapter (right) You can ignore the gap on the back as shown in the photo below.

 

There are two main ways to record with a high-resolution camera without a storage function: the “PC method” and the “non-PC method”

 

For how to use a PC, please refer to the page below.

 

For the non-PC method, use an HDMI recorder.

We sell the following HDMI recorders.

HR-MINI HDMI recorder

 

As mentioned above, no PC is needed, all that is needed is to connect the monitor and camera using an HDMI cable.

 

 

 

 

You can save images and videos to a microSD card or a USB memory storage device connected to the main unit.

To install an external hard drive and record for a long time, please refer to the page below.

The XM200HD uses a dedicated remote control to save images.
If you just want to save images, you can control it from outside without using the remote control.

The terminal on the remote is a pre-made 3-pole 3.5mm stereo mini plug Right on the website that is easy to get.

 

 

No problem even if you disconnect the optional remote control and use it.

 

If you disconnect the remote control and use it, insert a resistor (30KΩ) between the white wire and yellow wire to short circuit and a static image will be saved. (Make sure the resistance is 30KΩ.)

 

 

 

XM200HD high performance high definition camera

Our high resolution cameras and PC monitor direct connection cameras have USB ports. Normally, USB memory will be inserted here.
The captured images will be saved to this USB memory.
To view saved images, it is necessary to remove the USB memory and connect it to the PC.

 

We’ll show you how to send captured images directly to your PC or tablet without having to move USB memory.

 

It’s called an SD card with built-in WiFi or a wireless SD card.

 

Connect this port to the camera’s USB port using a USB-SD adapter.

 

 

Installation methods vary slightly depending on the card manufacturer, but the two steps below are required.

 

1. Download the application from the manufacturer’s website
2. Connect the SD card to Wi-Fi and make the Wi-Fi compatible PC recognize the card

 

After the installation is complete, you can perform some operations as shown below.
The screen above is a live image connected directly to the camera.

The captured image will be saved on the screen below (Tablet).

 

After releasing the camera shutter, you need to update your PC or tablet, but if you press the “F5”- function key and reload, you can immediately check the latest capture.

 

There is also an SD card with built-in WiFi that supports the cloud. If you use this feature, your images will be saved in the cloud.

There are many different types of wireless SD cards on the market, but please understand that we cannot guarantee that all cards will work when used with our cameras.
In our company we are using Toshiba’s Flash Air.
We also tested the operation of the older Eye-Fi model and confirmed that there were no problems.

However, for some reason, Eye-Fi’s new model (cloud compatible) did not work properly with our camera.

 

※In case you have saved an image but suddenly cannot save it, there are two common reasons.

 

①Application cases, etc. of the WifiSD card you are using has been updated automatically. If the Wifi SD card is updated automatically, the Wifi settings may be disconnected. By resetting, the image will be recognized and saved

 

② In case the SD card reader cannot recognize it
Because the SD card reader has surprisingly unstable contact, when the SD card is a little off it is largely unrecognizable.

Our cameras can show whether the image storage media on the catalog is normal or abnormal.
If there is no camera symbol in the list of images below, if the camera symbol is not recognized, it will be recognized.

 

 

If it is not recognized, please take measures such as removing and inserting the SD card or replacing the card reader.

 

※These wireless SD cards are an introduction only and are not guaranteed to work with all models. So please check before use.

 

Additionally, if with the high performance XM200HD high resolution camera, you can check the captured images using the camera functions without transferring the MicroSD card to PC.

There is no length limit in the HDMI standard, but metal cables are typically up to 15m.
Most cables on the market have a length of up to 15m.

When looking, they are probably sold up to about 20m high.

 

However, there are different types of extenders on the market that can be used to extend lengths beyond 100m.

Below is an extender that uses coaxial cable and allows extension up to 120m.

 

There are several ways to import high-resolution camera signals into a computer.

One way is to use a capture board.

However, you will need a desktop computer and since you will have to open the computer and set up the board, you will also need minimal knowledge about computers and equipment selection.

Therefore, we will introduce converters that can be used regardless of the shape or type of computer.

 

HDMI→USB3.0 adapter

 

The image below is the HDMI⇒USB3.0 (GV-USB3/HD) adapter from IO Data Devices.

If your PC has a USB 3.0 port, you can use it with a laptop or desktop.

If you install the software from the included CD, you can easily capture still images and video and can also play it back immediately on your computer.

 

 

It has the advantage of avoiding the hassle of removing the USB memory or SD card from the camera and inserting it into a PC, but because it is connected via USB, real-time performance is slightly worse than when connected directly to screen .

Additionally, the PC needs a USB 3.0 port and it will not work with a USB 2.0 port.

 

Furthermore, the high resolution camera can be used with standard measurement software for microscopes.

Calibration is performed on two axes: XY.

Normally, calibration is performed using two axes, but to simplify calibration even a little, our high-resolution camera uses a method that allows you to click any three points on the ring. round.

 

Calibration will improve if you use the monitor as much as possible.
(Even though a small portion can be corrected, the error will be large. (Accumulated error))

Therefore, it is necessary to choose a circle as large as possible.

Not all circles need to be reflected.

 

It’s good if you can get any three points on the circle as big as possible.

 

Calibration can be performed in any of the following ways. However, the error increases when (A) > (B) > (C).

 

（A)	（B)	（C)

 

It is not necessary to see the entire circle.

For example: Can be calibrated by selecting three points as shown below.

The time you can record video with just a high-resolution camera is limited.

There are two main ways to record long videos lasting several hours: the “PC method” and the “non-PC method.”

 

If you use a PC, you can record video directly to your PC’s storage, allowing you to record over long periods of time.

 

 

If you are not using a PC, you can use our HDMI recorder by connecting an external hard drive.

HR-MINI HDMI recorder

 

By connecting a large capacity external hard drive (up to 1TB) instead of USB memory, you can record for long periods of time.

 

Note that USB external hard drives will not work

Be sure to use a self-powered external hard drive that requires its own power source.

 

Also, if the format is FAT32 then there is a limit of 4GB per file, so if you want to record a long video in one file, please use an NTFS formatted HDD.

※It does not work with exFAT.

If you want to view images from a monitor-type camera directly on one screen at the same time, you will need a device called a “split device”.

1. Connect two high-resolution cameras (single-function type)

This usage is usually simple and can accommodate 2 cameras

※Product code：YHD-M21

 

 

There are two conversion modes.

 

●Half-screen mode

 

●The image display mode from the first camera shows the full screen and displays the second camera in a smaller size.

A blood draw is a medical procedure.

There is a special microscope that allows you to examine blood flow without drawing blood.

It seems like many companies sell them, but I think the set below is the cheapest.

Here is the set of photos below.
A hard case to carry the monitor is also included.

 

	Fixed stand
How to observe blood flow
	Observe with the ring finger on the opposite side of your dominant arm. If you can’t see with your ring finger, use your middle finger.     First, apply the included oil to the thinnest part of the nail (nail base) with a cotton swab. (See photo on the left)
	It is not a special oil. It is also easily available on the internet.
	Insert your ring finger into the holder to determine approximate position.     Final fine-tuning is done using the focus adjustment dial on the microscope side.
